Method of establishing an oscillator clock signal

A hybrid numeric-analog clock synchronizer, for establishing a clock or carrier locked to a timing reference. The clock may include a framing component. The reference may have a low update rate. The synchronizer achieves high jitter rejection, low phase noise and wide frequency range. It can be integrated on chip. It may comprise a numeric time-locked loop (TLL) with an analog phase-locked loop (PLL). Moreover a high-performance number-controlled oscillator (NCO), for creating an event clock from a master clock according to a period control signal. It processes edge times rather than period values, allowing direct control of the spectrum and peak amplitude of the justification jitter. Moreover a combined clock-and-frame asynchrony detector, for measuring the phase or time offset between composite signals. It responds e.g. to event clocks and frame syncs, enabling frame locking with loop bandwidths greater than the frame rate.

Clock synchronizer and method of establishing an output clock

A hybrid numeric-analog clock synchronizer for establishing a clock or carrier locked to a frequency reference. The clock synchronizer is typically a clock multiplier and a jitter attenuator. The reference may have a low update rate. The synchronizer achieves high jitter rejection, low phase noise and wide frequency range. It can be integrated on chip.

Method for sampling output from a grid based digitizer sensor

Signals from a plurality of sensing lines of a grid based digitizer sensor based is combined based on matrix multiplication with a Hadamard Matrix. The combining provides a plurality of signal combinations. Each of the plurality of signal combinations is sampled with a different Analog to Digital Converters (ADC) in a group of ADCs. The sampling is performed simultaneously. The sampled outputs from the group of ADCs are post processed including multiplying an inverse of the Hadamard Matrix with the sampled outputs from the group of ADCs. The presence of an object interacting with the grid based digitizer sensor is detected based on the post processing.
